Respect for persons, beneficence, and justice are bedrock ethical principles in science. They are especially important when studying vulnerable populations. Billias et al. argue that deception is necessary to assure the internal validity of their exercise study involving people living with long COVID.[1] Here, we assert the use of deception is ethically indefensible and scientifically unnecessary in this population. It undermines informed consent, increases risks for harms, exploits the vulnerability of participants, and erodes trust in science and health care, all while exploring a question that already has been asked and answered satisfactorily enough to inform clinical recommendations.](https://files.mastodon.social/cache/media_attachments/files/115/692/301/248/925/906/small/d198416bc80781cb.png)










![Extracellular vesicles from long COVID patients promote RUNX2-mediated cellular stress via dysregulated miR-204 and p53 pathway activation — Dalle Carbonare et al.
"Our study demonstrates that LC-EVs carry a distinct molecular signature capable of inducing significant cellular alterations […] enriched in markers of platelet activation and contribute to a pro-thrombotic environment" "Upon entering target cells, LC-EVs promote the expression of RUNX2 and activate stress-related pathways involving p53, p21, and Sestrins, indicating a response to cellular stress […] showing impaired mitochondrial adaptability under metabolic strain, potentially explaining fatigue and exercise intolerance in LC patients."](https://files.mastodon.social/cache/media_attachments/files/115/658/856/064/425/567/small/4a55b23399ececb0.png)
